I have a '96 Eddie Bauer Limited and it has the same problem. They told me that there is a small butterfly valvu located in the vac lines to select between hot or cold air. There is a tension spring connected to the valve, to an acutator, and to your ac contorl system. The spring on mine broke, so the valve opens and closes due to suction only. It is supposed to be about a $700.00 fix (due to the valves location by the firewall) but I have found a way around that. Try to aggressively apply the brakes making the vehicle slow rapidly, and at the same time turning on the blower fans with full bast heat selected. If this does not work, try doing the previous while going around a right hand corner. The corner will help the momentum of the valve turn in the right direction. Remember you have to switch the fan on full blast when you try either. If it works you should hear a thud as the valve flips shut and the heat should start coming out of the vents.

I had a heater core problem on a Ford pick up. The problem was the core was pluged up from a stop leak formula I put in the radiator. I had to flush the stuff out of the heater core about 3 times with a garden hose.

Sway bars are there to give cornering stability when steering and as such is a safety requirement. The link will be cheap and easy to replace so why waste time and risk safety to put it off. As to the heating problem and I would be checking the control module that allows the heater tap to turn on as it appears that there is insufficient coolant getting into the heater either from a tap half on or blocked hoses/core.

check your heater control cable and check your coolant control valve for vacuum operations. control valve located under hood @ coolant hoses leading to the heater core. cable operates a blend door inside truck under dash/behind glove box.. this should help

Engines can rock on the motor mounts. You probably have a vacuum line that is pinched, cracked, broken,kinked, or unhooked. check the engine compartment lines first. If you have thin plastic vacuum lines, they can kink more easily than rubber lines. If you have been working under the dash (replacing a radio, etc) check your work area in case you have a broken fitting on a vacuum housing or an unhooked line.

most likely either the vacuum line to the round ball is disconnected allowing the vacuum pressure from moving the inner levers to the heating unit of ....check your radiator fluid levels to ensure they are to specifications level ...or you may need a radiator flush to flush the heater-core as they become plugged from gunk also could be the line going into the heater has become lose you will need to get involved a bit under the dash to investigate this ....also the switch could be bad or yes by all means use a test light and see if your fuse has blown it may be as well vacuum lines under the hood has dry-rotted preventing proper vacuum to the unit

but it sounds as if you need to have the heater core flushed these are the areas in which i would start with first ...good luck and i hope this helps you

If the car is not providing heat and thermostat is good, then your problem is a faulty heater core. Sometimes when heat cores wear out, they sometimes give off an anti-freeze smell.You can go to autozone.com and register for full free online repair manual with everything you could need for your car.

hmmm tricky, at a long shot it could be the heater control switch in the engine bay, u should be able to see this working if you get someone to sit in the cab and move the temp switch from cool to heat over and over. if this is working ok try bleeding or flushing your heater pipes. considering your getting heat when your moving but not at idle im leaning more to the bleed side of it, you could have an airlock. this would be overcome when the engine is at higher revs therefore pumping a higher volume of water and also at a faster rate through you heater lines temporarily fixing it
